Filed: 1985-03-20
Abstract: PURPOSE:To enable to grow crystal at a low temperature by a method wherein a hydrogen-atomic stream, in which electron spin is deflected in specific direction, is made to irradiate on mixed gas and a substrate. CONSTITUTION:A hydrogen-atomic stream, in which electron spin is deflected in specific direction, is made to irradiate on mixed gas and a substrate when an organic metal vapor-phase growing (MOCVD) method, a molecular beam epitaxial growing (MBE) method, or ion cluster beam (ICB) method is performed. In the MOCVD method, the spin of hydrogen-atoms is returned to antiparallel condition by the hydrogen-atomic stream, wherein electronic spin is deflected, coming into collision with the grains of the mixed gas, and the decomposition of the mixed gas is accelerated by the energy discharged at that time. Besides, the substrate is locally heated up by the energy generated by the hydrogenous stream projected to the substrate, and the growth of the crystal layer on the substrate can be accelerated. On the other hand, in the MBE method or the ICB method, as the substrate can be locally heated up by the irradiation of the electron spin deflected hydrogen-atomic stream, the device can be maintained at a low temperature, and the crystal growth on the substrate can be accelerated.

Filed: 1978-05-15
Abstract: PURPOSE:To decrease the leak power for the antenna device used at plural frequency bands and thus to enhance the performance of the antenna device by securing the special mirror surface at the periphery of the subreflector. CONSTITUTION:Mirror surface part S1S2 and A1'S2' of the special shapes are formed at the periphery of central mirror surface S1S1' of subreflector 4 featuring a hyperboloid containing focal point F1 and F2. Now, the loci at the point where the  electric waves reflected from periphery part M1M2 of main reflector 3 feature the  equal phase is referred to as M2M2' respectively. Thus, the locus forms an arc centering on point O on the straight line parallel to the axis of the reflector and passing through point M1. This arc forms curve S1S2. As a result, the electric wave  from F1 is refleted on surface S1S' in the high frequency band, and then goes  toward mirror surface M1M1' of reflector 3. Thus, the leak power is reduced. While  in the low frequency band, the phase error is reduced by reflector 4 of a special  shape thus to decrease the leak power. In such way, the leak power can be decreased for the antenna device used at plural frequency bands, thus enhancing the performance of the antenna device.

Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a heater by melt of a heater holder and internal stress (thermal stress) of the heater, by placing a metallic member in the vicinity of the downstream side of a pressure roller. SOLUTION: In this device, the metallic member 30 is placed in the vicinity of the pressure roller 11 on the downstream side and near below it so as to cover the pressure roller 11 along the length direction of the heater 14 and the pressure roller 11.

Moreover, the heater 14 is prevented from the breakage by the internal stress (thermal stress) of the heater 14 caused by the differential of the thermal expansion quantity between the heater holder 10 and the heater 14, originated form the temp. differential between the recording paper P passing part and the recording paper P non- passing part.
